Personal data policy

This policy explains what personal data Entrena processes, why, who sees it and how to exercise your rights. It is governed by Colombia's Ley 1581 de 2012, Decreto 1074 de 2015 and related data protection rules. The Spanish version governs; this is a courtesy translation.

1. Who is responsible

The data controller is bychris.agency, which operates Entrena. You can reach us at hola@bychris.agency about anything to do with your data.

Each trainer using Entrena is responsible for their own clients' data. We act as a processor for that information: we handle it on the trainer's instruction and use it for nothing else.

2. What we process

About the trainer

• Name, WhatsApp number and email address.
• What they record about their business: classes, schedules, rates and payment status.

About the client

• Name and WhatsApp number, entered by their trainer.
• Tracking data you record: weight, body measurements, energy, sleep and the notes you write.
• Your meal plan and the meals you mark.
• Your sessions, class spots and payment status.

Weight and body measurements may count as sensitive data because they relate to health. Processing them is therefore voluntary: you are not required to record them and the app works without.

3. Progress photos

In this version progress photos are stored only in the browser on the device where they were taken. They are not uploaded to any server, they never travel over the network, and we have no way to see them. Clearing browser data or removing the app deletes them, with no copy anywhere.

4. What we use the data for

• So your trainer can follow your progress and adjust your plan.
• To show you your schedule, your classes and your payment status.
• To run and maintain the service.

We do not sell your data, do not share it with third parties for advertising, and do not use it to train AI models.

5. Who can see it

Only your trainer. Other people in your group or classes do not see your information. The bychris.agency team accesses it only where necessary for support or to fix a fault, always under a duty of confidentiality.

The invite link sent to you is personal. Anyone holding that link can enter your space, so don't share it. If you think someone else has it, ask your trainer to generate a new one.

6. How long we keep it

For as long as your relationship with your trainer lasts, plus any period the law requires. When that ends, you can ask for deletion and it is deleted.

7. Your rights

As the data subject you may at any time:

• Find out what data we hold about you and how we use it.
• Ask for it to be corrected if it is wrong or incomplete.
• Ask for it to be updated.
• Withdraw your consent and ask for deletion, unless a legal duty requires us to keep it.
• Complain to the Superintendencia de Industria y Comercio.

To exercise them, write to your trainer or directly to hola@bychris.agency. We answer queries within ten business days and complaints within fifteen, as the law requires.

8. Consent

Before your first entry we show you what is stored, who sees it and how to have it deleted, and ask for your express consent. If you don't give it, nothing is stored.

9. Security

We apply reasonable measures to protect the information. No measure is perfect: if an incident affects your data we will tell you, and notify the authority where required.

10. Minors

Entrena is intended for adults. If a minor is going to use it, consent from whoever holds parental authority is required, and processing is limited to what is strictly necessary, respecting the child's best interests.

11. Changes

If we change this policy we will publish the new version here with its date. If the change is significant, we will tell you inside the app.
